Definitions

  • the invention relates to a vacuum cleaner with a suction unit and a filter container, through which the air drawn in via the suction unit passes and dust which filter container is freed by a filter liquid, e.g. Water, is at least partially filled.
  • a filter liquid e.g. Water
  • the object of the invention is therefore to provide a vacuum cleaner of the type mentioned to indicate at which the duration of action of the filter fluid greatly increases and the output is greatly reduced by harmful germs.
  • this is achieved in that in the filter container at least two with the Electrodes in contact with, preferably immersed in, filter liquid Silver or a silver alloy are arranged and that a voltage source is provided, which can be connected to the electrodes.
  • the formed in the filter liquid by applying a voltage to the electrodes Due to their disinfectant effect, silver ions prevent the development of germs Bacterial populations. In this way, the filter fluid keeps its dust-separating effect compared to known vacuum cleaners of this type very long period of time and a danger to the environment from filter liquid droplets, This can prevent the air stream being carried away.
  • the voltage source preferably low-frequency, DC voltage pulses generated.
  • the inside of the filter fluid The pulsating current caused increases the number destroyed by silver ions pathogenic germs.
  • An embodiment of the invention may consist in that the frequency of the DC voltage pulses in the range of 2 to 6 Hz, preferably 4 Hz.
  • the mentioned range, in particular the value of 4 Hz, is largely independent of the height the applied voltage a particularly strong reduction compared to other frequencies the germs and bacteria contained in the filter fluid.
  • the voltage source comprises a battery or an accumulator which is connected to a DC-DC converter is connected.
  • Another variant of the invention can consist in that the battery is a 9V battery and that the DC-DC converter has an output voltage of 30V, which with a pulse frequency of 4Hz is clocked.
  • a further embodiment of the invention can consist in that the Voltage source an isolating transformer, a rectifier and a pulse shaper includes.
  • the isolating transformer also fulfills the usual safety-related requirements Pads.
  • a further increase in the germicidal effect can be according to another Achieve embodiment of the invention in that the filter container contains an opening, About which the filter water a sodium chloride solution and / or a silver colloid solution can be added.
  • the chlorine ions formed by the current flowing between the electrodes represent one Help to remove the filter fluid present at the beginning of the current flow Germs because the disinfection process based on the silver ions takes a longer start-up time needed.
  • the addition of a silver colloid solution increases the number of for Sterilizing effective silver ions in the filter liquid.
  • Fig. 1 shows the schematic structure of an embodiment of the invention Vacuum cleaner.
  • Fig. 1 shows a vacuum cleaner 1 which has an inlet 8 which e.g. about one not hose shown is connected to a vacuum cleaner brush, small particles, e.g. Dirt particles sucked in together with the air flow drawn in by one Filter container 4 are passed through, which with a filter liquid, e.g. Water 5, is at least partially filled.
  • a filter liquid e.g. Water 5
  • the filter liquid 5 be replaced.
  • the suctioned in via the inlet 8 and in a pipe socket 10 into the filter liquid 5th initiated air flow is generated by a suction unit 3, which is in the upper part of the Vacuum cleaner 1 is arranged.
  • a suction unit 3 which is in the upper part of the Vacuum cleaner 1 is arranged.
  • the filter liquid 5 inside the filter container 4 is an additional, optional one Particle filter 2 arranged, the 5 when the air flow exits the filter liquid particles thrown up.
  • the trained by the suction unit 3 Vacuum causes the air flow flowing through the filter liquid 5, which enters the vacuum cleaner 1 via the inlet 8 and the pipe socket 10 and after Flow through the filter liquid 5 through the particle filter 4 sucked into the suction unit 3 becomes.
  • the dust in the filter liquid 5 is freed from sucked in air stream expelled again through the outlet 9, where it reduces pollution the environment is released. Due to the air flow in the filter liquid 5 precipitating particles, the most diverse pollutants, such as heavy metals etc., but also Containing pathogens and germs begins in the filter liquid 5 within a very short time Time a strong multiplication of these pathogens and germs, by a clear Darkening of the filter liquid becomes visible. Ultimately, this process leads to: the filter liquid 5 loses its cleaning effect almost completely and on the contrary Outlet 9 ejected airflow contains water droplets, which together with dangerous Germs and pathogens are released to the environment and therefore the Functionality of the vacuum cleaner severely impaired or this one Health risk.
  • the filter container 1 at least two with the Filter liquid 5 in contact, preferably immersed in, electrodes 6 Silver or a silver alloy are arranged.
  • the electrodes 6 are not one Switch shown connected to a voltage source 7.
  • the voltage source preferably generates low-frequency, DC voltage pulses which the electrodes 6 are applied and a current pulsating at a low frequency result in the filter liquid 5.
  • the frequency of the DC voltage pulses is preferably in the range from 2 to 6 Hz, where 4 Hz, based on a DC square wave signal when performed Test series has brought the best results in terms of the degree of disinfection.
  • the voltage source is a battery or a Includes accumulator, which is connected to a DC voltage converter. So it can Battery e.g. be a 9V battery, with the help of the DC converter Output voltage of 30V generated, which is clocked with a pulse frequency of 4Hz. So for example, a housing attached to the side of the vacuum cleaner according to the invention Commercially available 9V battery included, which is easy for the user can be exchanged.
  • the Voltage source an isolating transformer, a rectifier and a pulse shaper comprises, the isolating transformer on its primary side with the mains voltage and on its secondary side is connected to the rectifier.
  • the output voltage of the The rectifier is then converted into a pulsating DC voltage by the pulse shaper converted, which is applied to the electrodes 6.
  • silver colloid 5 can be added to the filter liquid in order to Increase the number of silver ions in the filter liquid 5.
  • An opening (not shown in FIG. 1) can therefore be formed in the filter container 4, Via which the filter liquid 5 a sodium chloride solution and / or a silver colloid solution can be added.
  • a sodium chloride solution and / or a silver colloid solution can be added.
  • the addition of the sodium chloride solution or Silver colloid by lifting the suction unit 3 from the vacuum cleaner 1 and direct Pour into the filter liquid 5.
  • the latter solution or Mixed liquid from sodium chloride solution and / or silver colloid solution into the Filter liquid 5 especially in the water, can be a quick onset Disinfectant effects are caused at the initial stage, in which the by the Silver ion-induced cleaning effect is only started relatively slowly bridged.
